  exam. All students took the exam. The researcher uses a computer statistical software package to compare the mean score of subjects in group 1 and group 2. This results in statistics of t = 2.84, degree of freedom (50 + 50 = 100  2) = 98, and p =.03. Which statistical test, if any, was conducted in this study? 1. An independent sample t test.
  2. A dependent sample t test.
